Filed: 1970-04-03
Abstract: 1302739 Automatic voltage control GARRETT CORP 3 April 1970 [3 April 1969] 16017/70 Heading G3R [Also in Division H4] In a pulse width modulator, a capacitor 20 shunted by a diode clamp 28, is charged via a transistor 12 at a rate determined by an input signal applied to the base of the transistor, Fig. 2 (A) 21, the potential at point A rising until a normally non-conducting transistor 22 conducts, thus increasing the base current of transistor 12, and the positive feedback action causing both transistors to saturate. Negative feedback via element 14, which may be resistive, inductive or capacitive, stabilizes the stage 12. They remain in this condition until a pulse (C), which may be supplied by a separate oscillator or derived from the output of the circuit, is supplied via diode 30 to discharge capacitor 20 thus turning off transistor 22, the width-modulated pulses (B) being taken from point B. The modulator may be included in a voltage regulator in which the regulated output is compared with a reference voltage and any error signal is converted to pulse width modulation to control a regulator developing the regulated output voltage.

Patent GB-367262-A (GB)
Title: Improvements in or relating to cans or like metal containers
Filed: 1931-06-02
Abstract: 367,262. Cans &c. CONTINENTAL CAN CO., Inc., 100, East 42nd Street, New York, U.S.A.-(Assignees of Kronquest, A. L. ; 1016, East Water Street, Syracuse, New York, U.S.A.) June 2, 1931, No. 16046. Convention date, June 4, 1930. [Class 66.] In a can or like metal container of the type having a collar disposed within the body to extend above the lip of the opened container for engagement with a cap for reclosure purposes, one end of the collar which is straight engages in a housing formed by bending the other end of the collar upon itself. The can includes a body portion 1 and an upper end 2, secured by a double seam 3, and centrally depressed to provide a substantially vertical portion 4. Score lines 6, 7 are provided on the body to form a rip strip 8. A collar 9 is located within the container and is formed by folding a strip of metal longitudinally, cutting off the ends of the folded back portion 10, and folding one end of the inner portion of the collar to provide a housing for the other end 17 of this inner portion. The housing is formed by offsetting the end at 12 to form a portion 13 which is folded back on itself to afford the portion 14 which is again offset at 15 to provide the spaced portion 16 in line with the folded back portion 10. When the tongue 17 is housed within the other end of the collar the parts are compressed. The top of the collar is rolled at 11 into a bead, so that the collar may easily engage with a cap such as the inverted detached end 42 of the container for reclosure purposes. The collar may be slightly larger than the container and be forced therein to provide a tight frictional grip. Specification 351,149 is referred to.
Patent GB-587414-A (GB)
Title: Improvements in or relating to the picking mechanism of looms for weaving
IPC: D03D49/34
Filed: 1944-11-24
Abstract: 587,414. Hydraulic picking motions; shuttle box swells. HINDLE, T. Nov. 24, 1944, No. 16131. [Class 142 (iii)] [Also in Group XXIX] In a hydraulic picking mechanism, the shuttle is propelled by a piston in a cylinder 2, Fig. 9, acting through a lever 12 and a picking stick 52 so that the speed imparted to the shuttle is greater than the speed of the piston. A picking stroke is initiated by a cam 42 depressing a spring-loaded valve 41 which directs fluid to a pressure-shot valve 30 and sets it to put the pressure inlet 18 into communication with the rear end of the cylinder 2 As the piston nears the end of the ensuing stroke, a follow-up valve 20 operated by linkage 26 progressively cuts off the fluid supply and brings the piston to rest; the cam 42 subsequently releases the valve 41, causing the return of the valve 30 to its previous position and allowing a spring 16 to retract the piston in readiness for the next picking cycle. For pick-and-pick operation, the two picking mechanisms are controlled as shown in Fig. 9 by a cam 42, running at half crankshaft speed, actuating two valves 41 alternately. For pick-atwill operation, the valves 41 are placed side by side for actuation by a cam running at crankshaft speed and slidable along its shaft so that it can actuate either valve under the control of pattern mechanism. Or modified valves 41 may be employed having a plunger projecting from each end, picking being initiated only when both plungers are depressed; two cams running at crankshaft speed depress the plungers at one end of the two valves simultaneously on each revolution of the camshaft, but picking takes place only from the end of the loom corresponding to the valve 41 which has its second plunger depressed by the pattern mechanism.. Picking can be made dependent on there being an empty shuttle box to receive the shuttle by arranging each shuttle swell 66, Fig. 14c, to operate the plunger 49 of the modified valve 41 controlling picking from the opposite end of the loom. The swell pressure may be relieved whilst the shuttle is being picked by a cylinder 70, coupled in parallel with the corresponding cylinder 2, lifting a link 67 against the load of a swell spring 62. To cater for the swinging movement of the slay, the picking stick 52, Fig. 9, is operated from the lever 12 by a link 15 having a flexible end 15a, which can be coupled to any of a series of holes in the picking stick to adjust the picking impulse; adjustment can also be effected at 29 by altering the point at which the linkage 26 begins to slow down the piston. For details of the hydraulic components see Group XXIX.

Title: Improvements in or relating to the protective covering of electrical components suchas capacitors
IPC: H01G13/00
Filed: 1960-05-06
Abstract: 916,701. Laminates. SIEMENS & HALSKE A.G. May 6, 1960 [May 14, 1959], No. 16136/60. Class 140. [Also in Group XXXVI] A composite foil for covering an electrical component, e.g. a capacitor, comprises a metal foil, e.g. of aluminium, and at least one foil of synthetic resin or cellulose derivative laminated without the use of cement. The synthetic resin may be polystyrene, polyvinyl chloride, aromatic polycarbonates, and polyethylene terephthalate, and a suitable cellulose derivative is the acetate. The surface of the metal foil may be roughened or anodized, and the surface of the other foil may be softened by solvent action or heating, prior to laminating. As shown, a metal foil 1, Fig. 1, is laminated with one narrower foil 2, and one broader foil 3 of synthetic resin or cellulose derivative. When wrapped around the capacitor roll the foil 2 of synthetic plastic prevents the metal foil 1 from touching the leads. The areas of metal foil which are not coated with the narrower foil 2, enclose an empty space at each end of the tube, which is filled with casting resin. Printed markings, or code colours, may be applied at the contacting surface of either of the foils prior to laminating. Alternatively, (a) a narrow strip of metal foil may be sandwiched between two broader strips of synthetic resin &c. foil, one projecting beyond one edge, the other beyond the opposite edge, (b) a strip of metal foil may be sandwiched between two strips of synthetic resin &c. which leave one margin of the metal foil uncovered and project beyond the other margin (c), a rectangular strip of metal foil is laminated to a longer strip of synthetic resin &c., one end of which is narrower and one end broader, than the metal foil, (d) strips of synthetic resin, metal foil, and synthetic resin of progressively increasing width are attached end-to-end with a slight overlap. Roughened aluminium foil may be led from a roll 15, Fig. 7, through solvent 34, and pressed by rollers 23, 24 between outer layers of synthetic resin &c. foil from rollers 20, 22. The layers may be pressed together by rollers 26 or by high winding pressure, and heat may be applied by the rollers or by heat radiators 30.

Title: Deflector for magnetic compass
IPC: G01C17/38
Filed: 1922-06-10
Abstract: 181,382. Ogloblinsky, N. N. June 11, 1921, [Convention date]. Magnetic measurements.-In a deflector for use in determining the horizontal and vertical components of the directive force on a compass needle, vertically movable above the centre of the compass, two parallel magnetized bars are provided. These bars 18, 19 are carried by a sleeve 6 sliding on a graduated tubular column 1 provided with oppositely-disposed slots 2, 3, and the sleeve is adjustable in height by turning a milled head 8 on a shaft 7 mounted in the sleeve and provided with a pinion engaging a vertical rack within the columns. A set-screw 11 serves to lock the sleeve in adjusted position. The bars 18, 19 are fitted in sockets 16, 17 connected by a bar 20 which passes through the slots 2, 3 and rests in notches at the upper end of the sleeve 6 which is formed with flat portions 14, 15 against which bear flat surfaces on the sockets 16, 17. The bar 20 may be rotated so that the bars 18, 19 are either both vertical or both horizontal, and the parts are locked in either position by a ring 21, slidable and rotatable on the column 1, bearing on the upper faces of the sockets 16, 17, the ring 21 being retained in this position by lugs secured to the sleeve 6 and having a bayonetjoint engagement with a flange 22 on the ring. To the lower end of the column 1 is soldered a sleeve 33 formed with a horizontal flange 34 having four downwardly-extending projections 35 disposed 90‹ apart. An auxiliary magnet 55, used only when the horizontal component is being measured, is supported in V-shaped bases of apertures 54 formed in brackets 50, 51, Fig. 5, which are secured to opposed projections 35, and are connected by a sleeve 49 arranged on the column 1. The projections 35 are received in notches in a horizontal flange 46 of a sleeve 43 adapted to slide in a tube 36 secured to the centre of the alidade 40. The tube 36 is formed with opposed vertical slots in which are mounted segments 44, 45 secured to the sleeve 43. The segments are screw-threaded externally for engagement by a ring nut 48, rotation of which thus serves to raise or lower the sleeve 43 without changing the orientation of the deflector. In measuring the vertical component the compass is replaced by a dipping-needle, and the sleeve 6, carrying the bars 18, 19 in vertical position, is displaced vertically until the dipping-needle is brought into the horizontal plane.

Patent GB-681577-A (GB)
Title: Improvements in and relating to the manufacture of sponge rubber
IPC: C08J9/30
Filed: 1950-06-28
Abstract: Spongy articles having a cellular texture are made from Hevea latex or from an artificial latex obtained by colloidal dispersion of natural rubber by partially hydrolysing or breaking down the proteins e.g. by an enzyme such as trypsin or heating under pressure with NH3 or by natural ageing or by any other substance which can produce the same result, stirring, shaking or beating violently to produce a non-reversible cream or foam which coagulates in time or on heating without any addition of gelifying or coagulating agent.  A foaming agent e.g. soap may be added to the hydrolysed latex prior to the stirring to retard flocculation and accelerate the foaming. Alternatively or in addition the cream may be treated with NH3 water to dilute it and air can be enclosed in the mass by any known means. In an example Hevea latex concentrated to 58 per cent dry rubber content and ammoniated to 0.8 per cent is partially digested in 4 days with dry pancreas of pig powder at the rate of 1.5 grm/litre concentrated latex and then converted in a turboagitator to a non-reversible cream which is diluted with NH3 water followed by the addition of a stock soap make of oil palm and potash at the rate of 0.2 grm of soap per 100 grms dry rubber. The following dispersion is added per 100 grms of dry rubber: S 2 grms, zinc diethyldithiocarbamate 1.0 grm, zinc mercaptobenzothiazole 0.5 grm, water and dispersing agents as needed.  Air is incorporated by letting the diluted and compounded cream run down a sloped plate perforated with gauged apertures through which compressed air escapes.  The foam is poured into a mould and sets in 20 mins.
